Nephropathy In Type 2 Diabetes and Cardio-renal Events
Nephropathy in Type 2 Diabetes: Effects of an Intensive Multifactorial Intervention Trial on Cardio-renal Events.

The NID-2 study, a multicentric study (21 centres enrolled), was planned in two phases:

Phase 1(observational study, completed at 2007): after the identification of a type-2 diabetic population with typical DN, to study of the rate of renal and cardiovascular events during a middle term follow-up.

Phase 2(interventional study, started at 2007): after randomization in two groups, a group (intervention group) is treated with an intensive multifactorial intervention whose aim is to reduce morbidity and mortality due to diabetic complications. The other group (control group) continues the conventional therapy . To avoid bias in the treatment in each center, the randomization was performed for centre.

The same patients that completed the first phase of the NID-2 study (observation) were enrolled for the phase 2 of the study (intervention).

Diabetic Nephropathy
  • Drug: current therapy
    the patients have to be treated according the standard good medical practice by any center
  • Drug: irbesartan

    Therapy for hypertension:

    - Step 1: irbesartan 300 mg/die and ramipril 10 mg/die

  • Drug: ramipril

    Therapy for hypertension:

    - Step 1: irbesartan 300 mg/die and ramipril 10 mg/die

  • Drug: hydrochlorothiazide

    Therapy for hypertension

    - Step 2: Diuretic (hydrochlorothiazide 12.5-25 mg/die if serum creatinine <2 mg/dl, furosemide 25-75 mg/die if serum creatinin ≥2 mg/dl)

  • Drug: furosemide

    Therapy for hypertension

    - Step 2: Diuretic (hydrochlorothiazide 12.5-25 mg/die if serum creatinine <2 mg/dl, furosemide 25-75 mg/die if serum creatinin ≥2 mg/dl)

  • Drug: amlodipine

    - Step 5: doxazosin up to 4 mg/die

  • Drug: clonidine

    Therapy for hypertension

    - Step 6: clonidine

  • Drug: insulin

    Therapy for Hyperglycaemia (to achieve HbA1c <7):

    - insulin

  • Drug: simvastatin

    Therapy for hypercholesterolemia:

    - for reducing LDL cholesterol < 100 mg/dl: simvastatin up to 80 mg/die

  • Drug: fibrate

    Therapy for hypertriglyceridemia

    - for reducing triglycerides < 150 mg/dl and/or increasing HDL cholesterol > 40-50 mg/dl: a fibrate

  • Drug: erythropoietin

    Treatment of anaemia:

    - erythropoietin

  • Drug: aspirin

    Antiplatelet therapy (in all patients without contraindications):

    - aspirin up to 160 mg/die

  • Active Comparator: 1
    Control group patients will continue their usual therapy. During the study such patients could receive all the therapeutic modifications according to the good medical practice of the specialist.
    Intervention: Drug: current therapy
  • Experimental: 2

    An intensive multifactorial intervention is performed to achieve the goals for the following risk factors: hypertension, hyperglycaemia, lipids, anaemia.

    In particular, new antihypertensive drugs will be added one by one until the achievement of blood pressure target (<130/80 mmHg).
